Soaring fuel costs don’t just change travel habits, they keep some people at home

Soaring fuel costs have had a profound impact on the daily lives of Queenslanders, reshaping travel patterns and forcing difficult choices about mobility. As global tensions escalated and fuel prices surged, researchers from the University of Sydney's Business School conducted a comprehensive survey of 808 residents to understand how these changes influenced their behavior. The findings revealed that while many individuals adjusted their routines—driving less, using public transport more, and cutting back on non-essential trips—the effects varied significantly depending on demographics, location, and economic status.

The study, published on June 23, 2026, highlighted that as fuel prices climbed, the number of trips people chose to skip increased dramatically. At $2.50 per litre, nearly 90% of respondents indicated they would avoid trips; this figure jumped to almost 190% at $3 per litre and surpassed 270% at $3.50 per litre. These numbers underscore the financial strain placed on households, especially those with limited means. For many, the decision to limit travel wasn't merely about convenience—it was a matter of survival. Public transport, offering a fixed rate of 50 cents per trip in Queensland, became a more appealing option, yet its accessibility remains a challenge for those living in outer suburbs or rural regions where services are sparse or unreliable.

Dr. Andrea Pellegrini, the lead researcher, emphasized that transportation is far more than a simple expense. It is a lifeline that connects individuals to employment, education, healthcare, and social engagement. "Transport is not simply another household expense," he stated. "It’s what allows people to access work, education, healthcare, shopping, family commitments and social activities." This perspective highlights the broader implications of rising fuel costs beyond mere economics—they affect quality of life and personal autonomy.

The data also revealed distinct behavioral differences among groups. Older adults, particularly those over 60, were less likely to switch to alternative modes of transport such as rideshares or cycling, often prioritizing essential trips over discretionary ones. Full-time workers, despite driving more frequently, showed a greater reliance on public transport when fuel prices spiked, suggesting a shift in priorities during times of financial stress. Part-time workers, on the other hand, leaned toward more sustainable options like cycling and walking, reflecting a lifestyle that aligns with flexibility and proximity. Managers, meanwhile, demonstrated a preference for public transport, taxis, and cycling, indicating a balance between efficiency and affordability.

The research further noted that having bicycles at home correlated with an increase in walking trips, pointing to a growing trend of combining active travel methods. However, even with these alternatives, the study found that cycling saw only a modest uptick as fuel prices rose, while walking remained relatively unchanged. This suggests that while some individuals are adapting to new realities, others remain constrained by infrastructure limitations or lack of access to suitable equipment.

In addition to behavioral shifts, the study touched upon the broader economic landscape. Lower-than-expected fuel prices had a more pronounced effect on encouraging additional travel compared to the suppression seen during periods of high prices. This phenomenon indicates that once travel plans are set, they are harder to alter, especially when commitments are already established. Conversely, reduced fuel costs can alleviate budgetary pressures, enabling more spontaneous or leisure-based travel.

The period of the study spanned from mid-March to early April 2026, during which petrol prices fluctuated between $2.20 and $2.53 per litre. A relief came on April 1 with the implementation of a fuel excise cut, temporarily easing the burden on consumers. Meanwhile, the war in Iran triggered a surge in electric vehicle (EV) sales, with Brisbane's Rochedale—a traditionally car-dependent suburb—leading the charge in EV registrations outside the city center. Despite this positive trend, Pellegrini warned that the high initial cost of purchasing an EV continues to pose a significant obstacle for low-income households, many of whom are already struggling with the financial impacts of rising fuel prices.

Ultimately, the study underscores a complex interplay between economic factors, personal circumstances, and environmental considerations. While some Australians are making adjustments to their travel habits, the challenges faced by those in disadvantaged communities highlight the urgent need for policy interventions that support equitable access to affordable and reliable transportation. As fuel costs continue to evolve, so too will the ways in which people navigate their daily lives, balancing necessity with choice in an increasingly uncertain world.
